BT Sport app. Had the BT Sport channels through Plusnet. Plusnet have now done away with these channels, however i am paying for BT Sport through Plusnet which allows me to use the app. I can use the app without issue on my tablet. On my Roku device, after searching for BT Sport, BT Sport does not appear. On the Roku tv website, the BT Sport app appears, but this site will not allow me to add the app/channel to my Roku device. Suggestions please.
